   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   THE LOWER TO MID MISSISSIPPI VALLEY...

   ...SUMMARY...
   Thunderstorms, associated with isolated severe wind gusts and hail,
   will be possible on Thursday across parts of the lower to mid
   Mississippi Valley.

   ...Lower to Mid Mississippi Valley...
   An upper-level trough is forecast to move through the Upper Midwest
   and Ozarks on Thursday, as a cold front advances southeastward into
   the mid Mississippi Valley and Ark-La-Tex. Ahead of the front,
   surface dewpoints will be in the 60s F, enabling the development of
   weak instability as surface temperatures warm up during the day.
   Increasing instability and low-level convergence along the front
   will result in scattered thunderstorm development Thursday
   afternoon. Low to mid-level flow will weaken across the lower to mid
   Mississippi Valley on Thursday as the upper-level trough moves
   further away. This, combined with weak instability and poor
   low-level lapse rates will minimize any severe threat that develops.
   In areas that heat up the most, a marginal severe threat will be
   possible. The stronger cells could be associated with isolated
   severe wind gusts and hail.
